Lou shared the text exchange she had with her son, who claimed to be upstairs the whole time

“I turned to look at him and I saw the shape of someone turn away and then go up the stairs. I thought that was it.

“But my son heard me talking and texted me. He knew we were alone in the house so couldn’t understand why he could hear me telling him to ‘wait’ from downstairs. He was upstairs in bed so he thought it was really weird and texted me to ask me what I was doing.

“At first I thought he was winding me up. I assumed it must have been a prank – like I say, I always look for the rational explanation.

“However once he said he had honestly been in bed the whole time I became really freaked out.

“I know what I heard – it was clear as day a voice asking me what I was doing.

“It unsettled me so much that I had to go and check all of the rooms to check no one was there. I was sure someone must have been in the house with us.

“That’s why I want to share the picture now. I really want an explanation of what could be happening.

“I’m a sceptic and there could be a rational explanation for it all but there has been so much happening I feel I need an explanation to put my mind at ease.”

Since her encounter with the unidentified figure, Lou has shared the image she caught last year in her search for answers.
